Another approach would be to make a brass or bronze lap to fit the taper & then charge it with diamond lapping compound. If you have access to the equipment make an undersized lap from steel then spray weld it with bronze and finish machine it.
Then charge the bronze with the lapping compound.
Granted this would probably be the most expensive and time consuming way, but it should prove to be very accurate as long as the lap had the proper taper.
I have a set of MT taper hand reamers going up to a #5 (I think). If you want to use one just PM me. The only cost will be shipping both ways.
